` IMPROVEMENT 1N olEs'r-en` ORNAMENTING sH-EET METAL.

The Schedulereferred to in these Letters Patent and making pax-tof the seme.

To all whom itmaycoucern; i

Be itV known that I, CHARLES KAUFMAN, of; Oconomowoc, in the county 'of Waukesha and in the` State of' Wisconsin, have invented a'fnew and useful Improvementin Dies to be Employed in the Ornamentation of Sheet Metal; and I do hereby declareV the following to be a full, clear, and exact description ofthe same,.reference being had to 'the accompanying drawing making part of this specification, in which- Figure l is a perspectiveview of iny improved die. Figure 2 is a vertical transverse section of the die and the therein-inserted metal sheet.

Figure 3 is a plan view, in which'the die is represented'in twoparts, each part adjustable. t o The same letters of reference are employed in the several guresof the drawing. A y The nature of Inyinven'tion relates to theconstrnction of dies to be employed in the ornamentationof sheets of metal from which household and other wares are made; and My improvement consists in forming such die ina bplate of sheet metal by punching tneoutline ol' the desired design therein, leaving the base of the die thus formed connected with the plate and surrounded i upon the other sides by arim closely fitting Vthe out-l line vof the die, so that the metal sheet to be'ornamented can he inverted under the die resting -on the surrounding rim, and the outline of the ornament be sharply definedV by the combined action ofthe die and rim in the act ofistamping.

To enable those skilled in the'art to make anduse my invention, I will proceed to describe its construc-.A tion and operation.

In constructing these dies I employ a plate, A, of sheet metal, and cut the outline-of any desired'de-l sign throughit, by a sharp punch or other suitable in'- strum'ent, taking care that the eut maybe made as narrow as possible. "r I This ornamental out a terminates at each end in a straight cut, a', at right angles to its general `direction,'thereby forming a die, Al, connected at its base with the plate,1and surrounded upon Vits other sides by a-riin, A2, closely fitting the cut a ai.

',Scales A3 A3 may be formedV along the cutsa a', and adjustable' guides B B be-employed to determine the heightgor width ofthe ornament -to be-stamped upon the sheet of metal, and also determine the distance from the edgeofthe metal sheet. :f

In operating this ornamental die thesheet metal is clipped under the part A'1 resting upon the `-rim A,

with its edge abutting against the ,guides B B. The

impression can then ,be made by means of a hammer, or bypassingl the die with the sheet through snitable rollers, or by any-other preferred means..

, When the metal sheet to be stamped is very wide" an adjustable die on each edge of the shect may b ethe most convenient means of stamping or transfer-A ring the ornament over on Vsaid sheet.`

'lho die might also be Vso'constructed that the part `A1 could be adjustable, and allow different ornamental ldesigns to be placed in the same die.

Having thus described my invention,

What I claim, and desire to secure' by Letters Patent, iS-f- 1 1. The herein-described die for forming ornaments on Asheets of metal, consisting. of the parts A1 and A2, substantially as set forth. j

2, In combination with the parts Al and A2, the guides B B, substantially as specified;

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. C. KAUFMANN.
